NAME
    du - estimate file space usage

SYNOPSIS
    du [OPTION]... [FILE]...

DESCRIPTION
    Summarize disk usage of each FILE, recursively for directories.

    Mandatory arguments to  long options are mandatory for short options
    too.

    -a, --all
    write counts for all files, not just directories

    -B, --block-size=SIZE use SIZE-byte blocks

    -b, --bytes
    print size in bytes

    -c, --total
    produce a grand total

    -D, --dereference-args
    dereference FILEs that are symbolic links

    -h, --human-readable
    print sizes in human readable format (e.g., 1K 234M 2G)

    -H, --si
    likewise, but use powers of 1000 not 1024

    -k   like --block-size=1K

    -l, --count-links
    count sizes many times if hard linked

    -L, --dereference
    dereference all symbolic links

    -S, --separate-dirs
    do not include size of subdirectories

    -s, --summarize
    display only a total for each argument

    -x, --one-file-system
    skip directories on different filesystems

    -X FILE, --exclude-from=FILE
    Exclude files that match any pattern in FILE.

    --exclude=PATTERN Exclude files that match PATTERN.

    --max-depth=N
    print the total for a directory (or file, with --all) only if it
    is  N  or fewer levels below  the command line argument;
    --max-depth=0 is the same as --summarize

    --help display this help and exit

    --version
    output version information and exit

    SIZE may be (or may be an integer optionally followed by) one of fol-
    lowing: kB 1000, K 1024, MB 1,000,000, M 1,048,576, and so on for G, T,
    P, E, Z, Y.

PATTERNS
    PATTERN is a shell pattern (not a regular expression). The pattern ?
    matches any one character, whereas * matches any string (composed of
    zero, one or multiple characters). For example,  *.o will match any
    files whose names end in .o. Therefore, the command

    du --exclude='*.o'

    will skip all files and subdirectories ending in .o (including the file
    .o itself).
